The link you have posted is correct. It should bring up a page which has links to the WSDL files. One such link that you can try directly is this:
Note that the web services endpoint is defined in OID at this location:
Check the attribute "labeleduri;webservicesurl".
Check that the Workspaces GUI is up and running. Both the GUI and the web services endpoint are hosted in the OC4J_OCSClient instance. Use this command to check the status of that instance:
Thank for your information. But I can not find the attribute at OID you mentioned.
Do you have any idea why it is missing?
Is it related to installation procedure or do we have to install additional package?
The OID entry mentioned is created as part of the configuration process for Workspaces (which runs during the installation of workspaces - the config assistant at the end).
If that whole entry is absent from OID, then workspaces was not installed correctly. Is the workspaces GUI application working?
If ONLY the attribute "labeleduri;webservicesurl" is missing, then you may have a version of workspaces prior to 10.1.2.1 (in which web services were added). In that case, I would recommend upgrading to 10.1.2.3, which is the latest patch version.
